213.1 | Cadwell is one Heck of a circuit. | VANTEN::MITCHELLD | A number, not a free man | Tue Aug 28 1990 09:54 | 9 |
| I've raced there once. Have you been there before?
Its quite different to all the other club circuits.
The bits I couldnt get right were Charlies and the Gooseneck.
As regards getting a vast lump off your time. Try following somebody
who knows what they are doing i.e. they are are doing the time you want
do. I did this last time and got 6.5 seconds off my time in practice
(Snetterton) and lost a further 3 seconds in the race. I believe I've
got another 3 seconds to take off this time.

213.2 | various rates... | KOOZEE::PAULHUS | Chris @ MLO6B-2/T13 dtn 223-6871 | Tue Aug 28 1990 13:57 | 7 |
| I've noticed that various people have various rates at which they
approach their ultimate. I've particularly noticed corner workers when
they become drivers. Their first green flag laps are usually within 10
sec/lap (for lap times in the 1:10 to 1:40 range) of their ultimate,
and by the end of the first weekend (say 2 hr track time) they are
within 5 sec of their ultimate. This is quite a bit quicker than the
norm, but does show one benift of corner working. - Chris

213.3 | Lower Polar inertia? | CRATE::SAXBY | Is this personal or what? | Wed Aug 29 1990 04:44 | 6 |

A mid-engined single seater will always appear to loose grip more
suddenly than a front-engined saloon, it just takes longer to start
to loose it.

213.4 | Report | TRUCKS::DUGGAN_R | Don't happy, be worry | Mon Oct 15 1990 14:46 | 80 |
| My two days at Cadwell, were really good fun. From starting
out as the slowest of all of the 18 pupils on the morning of the first day, I
ended up over a second and a half quicker than anyone else and more than 5
seconds faster than the average. At the end of the first day I was about 3rd
fastest, but nearly 5 secs slower than the chap who was fastest, I think this
was mainly due to me not having done anything for the last 15 months, with
one exception everyone else there had either taken an advanced course just
recently or were already racing.
The two days the course consisted of:-
Assessment drive
46 Timed Laps in a Formula First 3 x 10 & 2 X 8 lap sessions.
A PI (Personal Instruction) session before each set of timed laps.
10 Demonstration Laps in a Multisports car (Van Diemon sports racer)
10 Laps in a Formula Forward (Budget slicks & wings formula).
Oversteer test.
In all around 100 Laps for 600 Pounds.
As for the driving you can see from the Lap times below, that I took fairly
large chunks off of my times on each set of timed laps.
All timed Laps 1 minute + seconds below.
42.18 29.2 23.56 23.77 25.47
44.96 28.57 31.73 20.78 24.88
42.3 26.16 20.76 21.79 22.32
41.39 26.82 20.86 18.66 16.81
49.28 27.89 24.25 19.47 14.09
35.85 30.1 21.28 19.6 16.92 } Bulked
37.89 29.35 22.74 17.13 *13.99* Best Time
42.65 29.66 14.99 } Started to run out of fuel S**T
17.05 16.27 }
I think the key to my improvement was the oversteer test. This was held prior
to the last session of laping. On one corner (Park) there is a large runoff
area, if its going to happen this is the 'best'? place to spin. The test
consisted of taking a run at the corner from halfway down the main straight
and from flat in third gear leave your braking to a cone placed at about
20 meters from the turn in point. This really takes some doing first time my
nerve went and I lifted at about 50 and was on the brakes a good 10-20 from
the cone, still convinced I was going to spin, the car just took the turn and
I exited to a deal of jeering from the onlooking instructors, next time round
I held the throttle to the cone and through the car in at the corner as hard
as I could, the result was pretty predictable, but there was a brief moment
when I thought I could hold onto it before it got away from me, and I exited
the corner backwards, still I did manage to keep the engine running. This
really is the quickest way to find the limit that I've experienced and of the
remaining three runs that I had I found that I could hold the car in a nice
power slide controlling it on the throttle and with minor steering adjustments,
in a total of a probably less than 20 seconds of action I had raised my
confidence in control of just over the limit situations by at least ten fold.
I certainly answered the questions that I had from .0 To give you some
idea of how fast the 1' 13.99 lap was compared to the
outright capability of the cars, the instructors reckoned that you could get
down to the 1 ' 15's by good and precise fast driving. Below this you have to
start pushing things, they set a final target of 1' 12 as they reckon the cars
are around a couple of seconds of the pace due to the way there set up and
that none of the engines are very quick, there was a race for the firsts the
weekend before I was there, the fastest lap during the race was a 1' 8.9.
It was only in the last set of ten laps (after the oversteer test) that I
felt confident of knowing how the car responded at and just beyond the limit.
And with all the laps in the session I never got a single lap where I felt
that in any one given lap I had taken more than about 50% of the bends as
well as I could. So I'm sure that I could find at least another second per lap.
After this I would have to start to stretching myself to find another whole
second but if the instructors assessment of the cars is correct that would
put me right up toward the front of the grid (or am I just dreaming 8*).
All I need now is M$ and I'd be able to find out.. oh well one day (Soon?)

213.5 | sounds good! | VANTEN::MITCHELLD | ............<42`-`o> | Tue Oct 16 1990 04:13 | 3 |
| But It will have to wait till next year when I have some more holiday. And
could be a bit difficult to persuade my sponsor/pit crew/transport driver
that this is better than a skiing holiday!
|
213.6 | Well I did it as well | VANTEN::MITCHELLD | ............<38`-`o> | Wed Feb 20 1991 11:08 | 2 |
| It was good. I managed a 1'15" but my excuse was the temp was below
freezing. Not too good for grip.

213.7 | Did you think is was good value? | TRUCKS::DUGGAN_R | Don't happy, be worry | Fri Feb 22 1991 08:32 | 25 |
| Derek,
Good to see you got there, any update on the course content and cost? I know
that the Other BHL circuits have put there prices up quite a lot just
recently. I think that its around 25%+.
How did it compare to running your own car at an open test day?
Unfortunately I'm just not in a position to be able to afford buy a car
for quite a while yet... oh well one-day. I know its a bit daft but I think if
they were to run a similar course at another circuit I would be quite
interested in having another go.
If you were to start out from the beginning again which other formulas would
you consider?
What would you say the advantages/disadvatges of buying a car as an
unfinnished project v's a going concern.
Regards,
Roy.

| >>How did it compare to running your own car at an open test day?
A lot better , I found someone in the same car shouting faster, smoother
a real help
>If you were to start out from the beginning again which other formulas would
>you consider?
Definitely Multisports, or Formula Forward, or even tin tops
FFirsts are a bit quirky, I didnt get them to go as fast as I should have
compared to the other vehicles. In the Escort I managed to get Instructor
going.. "I really enjoyed that, but a bit hard on my heart" (An ace FFirst pilot
at least 10 years younger than me). maybe I'm biased or feel more secure with
a bit of bodywork about me. Mind you the F.Forward I managed to throw around
quite well.
>What would you say the advantages/disadvatges of buying a car as an

Unfinished can mean a bottomless pit for money and time... my 23 has taken
a lot of both just trying to sort out small problems. �250 to get a throttle
that actually works. The fuel system will have cost about �150 to sort out.
The gear linkage will cost about �300 to finally sort. Oil cooling �150
Oil pressure gauge �50. etc.. etc..
I would buy a year old Multisport if racing was your aim, for about �8k
